Doubles Weighting Question

[Sawllkwa]

Just got my set of steel doubles and can't wait to jump in with them. Actually doing my first dive this weekend. I've been diving a while with a SS backplate and P weight with a single (80 cf) aluminum tank. Hope to take some tech diving instruction this late fall or winter, so I need to get used to the doubles. How much weight can I expect to use compared to my single tank set-up (ie: should expect more weight/less weight,...).

Thanks,

Depends on the tanks. In fresh water with my double 130's I don't use any weight.

Based on what you have told us,,,,you will probably need no additional wt. outside your steel doubles and SS backplate.

In Sweden? In a drysuit? I bet you will need a little additional weight. Try 4 kgs to start and see if you are neutral with ~25-30 bar in the tanks.

are things more buoyant in Sweden?

Thanks, actually just moved here from Vancouver so drysuit isn't new to me but I did have to invest in a new (thicker) undersuit.

heh, I've heard certain things are (Sorry ladies)

I think RJack just meant he is likely to have thick undergarments etc. so might need to add weight to compensate for that.

Well, I use the DUI 400 gm undies and I still don't need any weight in fresh. In salt, my brand new dui 400 gm might need a couple of lbs.

I echo Jeff - no weight when I'm using my 130's, salt or fresh, and I'm in a trilam with #200 undies. I'm not sure how I'd make out in Sweden though...

SS

SS

You will have to slap on another 8lbs, their gas is lighter
